触发dialog.close后，Word加载项停止工作. Office JS [英] Word add-in stops working after dialog.close is fired. Office JS
问题描述
我一直在研究Office365应用程序，在其中打开了对话框，并在执行某种活动后使用dialog.close()关闭了对话框.它工作得很好，但是功能区按钮停止工作，下次它将不再显示相同的对话框.
I have been working on an Office365 application where I opened a dialog and after some kind of activity when I close the dialog with dialog.close(). It works perfectly fine but ribbon button stops working and next time it will not show that same dialog again.
Office.context.ui.displayDialogAsync("https://" + location.host + "/Dialog.html", { width: 90, height: 90, requireHTTPS: true }, function (asyncResult) {
dialog = asyncResult.value;
dialog.addEventHandler(Office.EventType.DialogMessageReceived, processMessage);
if (asyncResult.status !== Office.AsyncResultStatus.Succeeded) {
return;
}
});
这是我的processMessage函数
and here is my processMessage function
function processMessage(arg) {
try{
var messageFromDialog = JSON.parse(arg.message);
var base64 = messageFromDialog.image.split(",")[1];
Word.run(function (context) {
var body = context.document.getSelection();
body.insertInlinePictureFromBase64(base64, Word.InsertLocation.replace);
return context.sync();
}).catch(function (error) {
app.showNotification("Error: " + JSON.stringify(error));
if (error instanceof OfficeExtension.Error) {
app.showNotification("Debug info: " + JSON.stringify(error.debugInfo));
}
});
if (messageFromDialog.messageType === "dialogClosed") {
dialog.close();
}
} catch (ex) {
console.log("Exception " + ex);
}
}
先谢谢您了:)

推荐答案
很抱歉，延迟调查此问题.长话短说，我必须对您的代码进行一些更改，以便它可以正常工作，它引发了一些异常(请参见下面的更改).我没有要插入的图像，因此我还假设您要发送给该方法的base64是有效图像.仅供参考，请更新4月21日发布的Office内部版本16.0.7967.2139，但这也适用于您引用的内部版本.
Sorry about the delay investigating this issue. Long story short, I had to do a couple of changes in your code so this can work, it was throwing a couple of exceptions (see changes below). I did not had the images you are inserting so I am also assuming the base64 you are sending to the method is a valid image. Also FYI please update Office build 16.0.7967.2139 was shipped Apr 21st, but this should also work on the build you cited.
这是我所做的更改:
- 我将这一行更改为仅获取属性:var messageFromDialog = arg.message; (为什么要解析JSON?)
- 我也很想这件事:如果(messageFromDialog ==="close")，我们没有messageType属性.(我们有类型) 顺便说一句，我的Dialog.html页面看起来像这样(我看不到您的页面，但我假设用户正在选择图像)
- I changed this line to only get the property: var messageFromDialog = arg.message; (why are you parsing JSON?)
- I also chagned this one : if (messageFromDialog === "close"), we dont have a messageType property.(we have type) BTW my Dialog.html page looks like this one ( I cannot see yours but i am assuming the user is selecting an image on it)

- 我还认为您不是在检查对话框是否已正确关闭，而是通过消息来完成操作，但是您需要订阅DialogEventReceived事件以了解用户是否关闭了对话框(而不显示消息).
function showDialog() {
var url = "https://" + location.host + "/Dialog.html";
Office.context.ui.displayDialogAsync(url, { width: 10, height: 10, requireHTTPS: true }, function (asyncResult) {
dialog = asyncResult.value;
dialog.addEventHandler(Office.EventType.DialogMessageReceived, processMessage);
if (asyncResult.status !== Office.AsyncResultStatus.Succeeded) {
app.showDialog("OK");
return;
}
else {
app.showDialog("whats up");
}
});
}
function processMessage(arg) {
try {
var messageFromDialog = arg.message;
var base64 = messageFromDialog.image.split(",")[1];
Word.run(function (context) {
var body = context.document.getSelection();
body.insertInlinePictureFromBase64(base64, Word.InsertLocation.replace);
return context.sync();
}).catch(function (error) {
app.showNotification("Error: " + JSON.stringify(error));
if (error instanceof OfficeExtension.Error) {
app.showNotification("Debug info: " + JSON.stringify(error.debugInfo));
}
});
if (messageFromDialog === "close") {
dialog.close();
}
} catch (ex) {
console.log("Exception " + ex);
}
}
